Description

Green shampoo composition for scalp care and method of manufacturing the same {Green shampoo composition for scalp care for preventing hair loss and method of manufacturing the same}

The present invention relates to a shampoo composition and a method for manufacturing the same. More specifically, the present invention relates to a shampoo composition and a method of manufacturing the same. More specifically, the present invention relates to a shampoo composition and a method of manufacturing the same. It is completely non-irritating to the skin and is environmentally friendly by using a variety of plant-derived extracts. It effectively removes hair nutrients and the sebum and stratum corneum of the scalp to protect the hair. It relates to a shampoo composition capable of promoting growth and a method for producing the same.

Humans have hair covering their heads to protect them. Although each person has different types of hair, the average number of human hairs is known to be approximately 100,000 to 120,000. Hair has a life cycle of development, growth, degeneration, and telogen phase, and it is said that it is normal for about 50 to 100 hairs that have entered the telogen phase to fall out per day. When hair grows for a certain period of time, it falls out and new hair grows. By repeating this cycle, the hair on the scalp is maintained.

Human hair generally grows for about three years before falling out, and new hair grows in its place again three months later. Considering that there are about 80,000 hairs, it is known that about 70 of them fall out per day, and about 70 hairs that fell out three months ago grow new, maintaining about 80,000 at all times.

However, modern people living busy lives today are under various stresses, and it is estimated that hair loss is aggravated by these stresses and the effects of aging. In the past, hair loss was recognized as being caused by genetics, but recently, it is widely recognized that hair loss occurs due to stress as well as aging.

It is assumed that alopecia is basically caused by the failure of the hair energy-generating function to function normally. This is because when the hair energy cycle does not function normally, energy deficiency occurs in the hair roots, and this negative effect is understood to hinder the normal growth of hair.

Testosterone, a type of male hormone known to interfere with the production of energy needed for hair growth and development, is DHT (Dihydrotestosterone) whose activity is increased by the action of 5 alpha-reductase distributed around hair follicles. ) changes to Activated DHT shortens the hair growth period by binding to androgen receptors, shrinks the size of hair follicles, gradually thins hair, and eventually causes hair loss.

As hair loss progresses, the hair papilla at the hair root becomes smaller, the thickness of the hair becomes thinner, and at the same time, the life cycle of the hair becomes shorter. If hair loss continues, the hair turns into fluff and the hair cycle becomes shorter, growing a little and then falling out, causing the hair to become thinner and less long.

Products have been developed and used to prevent this hair loss phenomenon or to help hair grow. However, when applying such hair loss prevention agents or hair growth agents, various side effects are observed due to imbalance in body homeostasis. Representative examples include various unexpected side effects such as decreased sexual function, allergies, depression, and local inflammation. In fact, hair loss is often caused by complex functional imbalances within the body, and treating such functional imbalances by limiting them to simple hormone suppression is seen as nothing more than a short-sighted prescription.

In contrast, anti-hair loss or hair growth compositions using various natural products that are not harmful to the human body have been proposed. These examples include those containing Gujeolcho, a type of wild chrysanthemum, as the main ingredient, mixed extracts of medicinal herbs such as Cornus officinalis and angelica root, or ingredients extracted from angelica roots and burdock roots as main ingredients, or ginkgo extracted from ginkgo leaves. Examples include shampoo compositions that contain dandelion extract as a main ingredient, dandelion extract, or cassia bark and sagebrush extract.

However, it is believed that no technology has yet been introduced to fundamentally prevent or treat hair loss by keeping the scalp healthy, hair follicles well, and growing hair healthy through the hair roots.

This product takes this into account and by keeping your scalp healthy, you can maintain healthy hair follicles and hair coming out through the hair roots can grow healthily. In addition, in order to keep young hair healthy, it effectively removes sebum and stratum corneum from the scalp using natural materials, supplies nutrients to hair roots and hair follicles, and protects against fungal bacteria (malassezia) that live on the scalp. This is an all-in-one scalp care green shampoo that is optimally formulated with ingredients that protect the scalp, prevent hair splitting, and give elasticity. Most of the ingredients are carefully selected from ingredients used in oriental medicine or food additives, so they not only do not irritate the skin at all, but also are harmless to the human body. Eco-friendly materials were carefully selected to avoid any problems with the natural ecosystem.

The following examples are considered representative of conventional technology.

The present invention uses plant extracts derived from nature for more than 90% of the raw materials used, and even in such cases, the foaming power and cleansing power are not inferior to those of conventional chemical synthetic products, and when these are mixed, the physical properties of each ingredient are improved. , In particular, there are factors that hinder product stability due to the difference in density, but stability is ensured through optimal mixing, and it leaves no residue when shampooing or rinsing, and provides a moist and soft feel to the scalp and hair.

The present invention has the advantage that it does not cause any skin irritation to the user's scalp and can be used in a safe and environmentally friendly manner.

In addition, the present invention has the advantage of protecting the user's scalp and keeping it clean by effectively removing the sebum and stratum corneum of the scalp.

In addition, the present invention has the advantage of activating hair follicles on the scalp, helping hair growth, and preventing hair loss by supplying appropriate nutrition to the scalp.

Figure 2 is a diagram comparing values regarding changes in scalp sebum (oil) as a result of testing the shampoo composition of the present invention in a circular bar graph.

Hereinafter, the present invention will be described in more detail and detail. It is clear that the specific numerical values or specific examples provided in the present invention are preferred embodiments of the present invention, and are only intended to explain the technical idea of the present invention in more detail, and the present invention is not limited thereto. In addition, in the specification of the present invention, detailed description of parts that are known in the technical field and can be easily created by those skilled in the art will be omitted.

The present invention includes the first step of adding various natural extracts to purified water and adding and dispersing functional substances that effectively remove the stratum corneum of the scalp and protect the area around the hair roots from various harmful bacteria so that hair can grow well.

In the first step, 21 to 39 parts by weight of purified water is added to the total amount in a mixing container, heated to 30 ℃ to 50 ℃, and 4.0 to 6.0 parts by weight of glycerin, 2.0 to 4.0 parts by weight of Houttuynia cordata extract, and 0.5 to 2.0 parts by weight of reishi extract are added. Parts by weight, brewer's yeast 0.5 to 2.0 parts by weight, Himalayan pink salt 2.0 to 4.0 parts by weight, polysorbate 80 1.0 to 3.0 parts by weight, dimethigonol 0.5 to 2.0 parts by weight, and propolis 0.5 to 3.0 parts by weight. This can be done in a distributed manner.

In the first step, glycerin and polysorbate 80 are used to effectively remove dead skin cells by acting on the stratum corneum of the user's scalp. When glycerin is added at 4.0 parts by weight or less or polysorbate 80 is added at 1.0 parts by weight or less, the effect of removing the stratum corneum is weak, whereas when glycerin is added at 6.0 parts by weight or more or polysorbate 80 is added at 3.0 parts by weight or more. In this case, the exfoliation effect does not increase compared to the amount input, so it is not desirable.

In the first step, Houttuynia cordata extract is used because it not only has an excellent anti-inflammatory effect by strengthening the capillaries of the scalp, but also has a good scalp regeneration effect. When the Houttuynia cordata extract is added in an amount of 2.0 parts by weight or less, the effect of dilating the capillaries of the scalp is weak, while when it is included in an amount of 4.0 parts by weight or more, the anti-inflammatory effect does not increase compared to the amount added, which is not preferable. Since the brewer's yeast contains a large amount of essential amino acids, it has a good regenerative effect on the body skin and scalp. Therefore, if brewer's yeast is included in an amount of 0.5 parts by weight or less, the scalp regeneration effect is weak, whereas if it is included in an amount of 2.0 parts by weight or more, the scalp regeneration effect is sufficiently compared to the amount added due to reaction with other ingredients. Because it is difficult to use, it is undesirable.

Additionally, in the first step, reishi extract and propolis protect the scalp from various harmful bacteria around the hair roots and help hair grow well. This can be achieved by utilizing the antibacterial, antioxidant, and anti-inflammatory effects of the reishi extract and propolis. If the reishi extract is added in an amount of 0.5 parts by weight or less or the propolis is added in an amount of 0.5 parts by weight or less, it is difficult to effectively protect the scalp from various harmful bacteria around the hair roots. On the other hand, if the reishi extract is added in an amount of 2.0 parts by weight or more, it is difficult to effectively protect the scalp from various harmful bacteria around the hair roots. When the propolis is added in an amount of 3.0 parts by weight or more, it is not preferable because the scalp strengthening effect does not increase compared to the amount added.

In addition, in the first step, Himalayan pink salt contains a large amount of minerals beneficial to the human body, and is also used to improve the cleansing power of the scalp by adjusting the entire composition to be slightly acidic. This is a natural salt that keeps the entire composition at a slightly acidic pH of about 5.5. If the Himalayan pink salt is included in an amount of 2.0 parts by weight or less, the cleansing power on the scalp is weakened, whereas if it is included in an amount of 4.0 parts by weight or more, the cleansing power is not improved compared to the input amount due to changes in pH. It is not desirable.

The present invention includes a second step to provide storage stability to the finally obtained shampoo composition.

In the second step, 0.5 to 2.5 parts by weight of carboxymethyl cellulose and 0.5 to 1.5 parts by weight of xanthan gum are added to the emulsification mixture obtained in the first step as described above, and the mixture is stirred at 1,000 to 1,500 rpm using a disper. This is done by dispersing at high speed to obtain a stable mixture.

In the second step, the carboxymethylcellulose and xanthan gum are used for the purpose of improving the storage stability of the composition of the present invention during distribution. If the carboxymethyl cellulose is contained in an amount of 0.5 parts by weight or less or the xanthan gum is contained in an amount of 0.5 parts by weight or less, storage is poor, whereas if the carboxymethyl cellulose is contained in an amount of 2.5 parts by weight or more or the xanthan gum is contained in an amount of 2.5 parts by weight or more If it is included in more than 1.5 parts by weight, it is not desirable because the storage stability does not increase in proportion to the amount added.

In the present invention, grapefruit seed extract can be used as a storage stabilizer or performance preservative for the composition of the present invention, and it is preferably used in an amount of 0.5 to 2.5 parts by weight based on the total weight. If used in an amount of 0.5 parts by weight or less compared to the total weight, the function as a product preservative cannot be smoothly achieved. On the other hand, if used in an amount of 2.5 parts by weight or more, the preservation performance may decrease compared to the amount added due to reaction with other components. It is not desirable because it is not effective.

The present invention includes a third step to improve the quality of the final product by providing a refreshing feeling to users after rinsing the shampoo, providing an herbal scent by smell, and replenishing the shine of the hair.

The third step provides users with the ability to further enhance their olfactory and visual effects after they use and rinse the shampoo composition of the present invention. For this, while cooling the mixture obtained in the second step to a temperature of 20°C to 30°C, which is room temperature, aroma oil was added in the range of 3.0 parts by weight to 6.0 parts by weight, and mixed at 10,000 to 10,000°C for 30 to 40 minutes with a Homer mixer. It is rotated at ultra-high speed at 25,000 rpm and milled to produce uniform particles. Aromatic oils include herbal oil, jasmine oil, peppermint oil, lavender oil, rosemary oil, eucalyptus, tea tree oil, and frankincense, and these oils can be used alone or in combination of two or more. When the aroma oil is included in an amount of 3.0 parts by weight or less, it is difficult to provide users with a sense of refreshing or olfactory satisfaction. On the other hand, when the aroma oil is included in an amount of 6.0 parts by weight or more, the aroma feels too strong, which is undesirable.

The present invention includes a fourth step of finally introducing and stabilizing the foamy material.

The fourth step finally enters the step of stabilizing the shampoo composition. This is done by mixing 25.0 to 30.0 parts by weight of coconut extract, a foaming material, with the homogeneous particles produced in the third step and stabilizing at a low speed of 200 to 300 rpm for 30 to 60 minutes. 25.0 parts by weight of the above coconut extract If it is included in less than 30.0 parts by weight, the shampoo composition does not penetrate well into the scalp and the foaming power is weakened. On the other hand, if it is included in more than 30.0 parts by weight, it is not preferable because the synergistic effect does not occur as much as the amount added to the shampoo composition. The foam in the shampoo composition allows it to penetrate well into the scalp. When a large amount of foam is generated on the scalp, it has the function of replenishing the scalp's stratum corneum for more efficient removal and assisting in supplying quality nutrition to the hair roots by cleaning the blood vessels of the scalp containing the hair roots. There is also

When these steps are performed sequentially, a shampoo composition that can prevent hair loss and accelerate hair growth promotion according to the present invention can be obtained.

The shampoo composition according to the present invention has the advantage of effectively removing dead skin cells from the scalp and activating the blood vessels of the scalp, thereby preventing hair loss and further improving hair growth. .

In general shampoo compositions, SLES (synthetic detergent) is used to secure cleaning power, but the present invention uses natural materials or natural extracts without using synthetic detergents, so that cleaning power equivalent to that of synthetic detergents can be secured. , it is possible to effectively remove dead skin cells without causing any irritation to the scalp.

Hereinafter, the method for producing the shampoo composition of the present invention will be presented as a more specific example.

Additionally, 10 g of carboxycellulose powder and 100 g of calcium hydrogen phosphate were mixed and added while the stirrer was set to 750 rpm. Additionally, 20 g of Carbopol 934 powder was mixed and added, and dispersed at 20,000 to 25,000 rpm to obtain a mixture. After that, when the dispersion state of the mixture is good, stop increasing the temperature and while cooling, disperse 5g of herb oil, 5g of jasmine oil, 8g of peppermint oil, and 10g of grapefruit seed extract, and gradually add 25g of brewer's yeast and 5g of dental silica to disperse. A shampoo composition was obtained. The final shampoo composition obtained was confirmed to be a dark brown viscous liquid.

<Result>

As a result of the performance test, when the product was tested by wrapping it directly on the tester's head, it was determined that the emulsifier did not penetrate into the scalp due to insufficient foaming power, and the cleaning power was low and the viscosity was high, making it less comfortable to use. The performance evaluation was as shown in Table 2 below.

<< Comparative Example 2 >>

575 g of purified water and 200 g of coconut extract were added by weight, the temperature was raised to 50-60°C, 10 g of polysorbate 80, 25 g of glycerin, and 10 g of reishi extract were added, and the stirrer was rotated at 300 rpm. Additionally, 15 g of carboxycellulose powder and 50 g of calcium hydrogen phosphate were mixed and added while the stirrer was set to 800 rpm. Additionally, 8 g of xanthan gum and 50 g of calcium carbonate powder were mixed and dispersed at 20,000 to 25,000 rpm to obtain a mixture. When the dispersion state of the mixture is good, the temperature increase is stopped and cooled to disperse 10 g of herb oil, 5 g of jasmine oil, 10 g of peppermint oil, and 7 g of grapefruit seed extract, and 25 g of brewer's yeast is slowly added and dispersed at 250 to 300 rpm to obtain a shampoo composition. The final shampoo composition obtained was confirmed to be a dark brown viscous liquid.

<Result>

As a result of the performance test, when the product was tested by wrapping it directly on the tester's head, the overall foam was richer, the cleaning power was increased, and the scalp felt strongly cool after rinsing. However, the hair felt stiff and had a strong viscosity, making pumping difficult, and the remaining liquid hardened after use, so it was confirmed to be unsuitable. The performance evaluation was as shown in Table 2 below.

<< Comparative Example 3 >>

575 g of purified water and 262 g of coconut extract were added by weight, the temperature was raised to 50-60°C, 20 g of polysorbate 80, 50 g of glycerin, 25 g of Houttuynia cordata extract, 15 g of dimethiconol, and 10 g of reishi extract were added, and the stirrer was rotated at 300 rpm. Additionally, 15 g of carboxycellulose powder was added and the stirrer was set to 900 rpm. Additionally, 8g of whole carbon gum powder was mixed and added. The mixture was mixed using a homomixer, the rotation speed was set to 10,000 to 25,000 rpm, and high-speed milling was performed for 2 to 3 minutes. When the dispersion state of the mixture was good, the temperature increase was stopped, and while cooling, 10 g of herb oil, 5 g of jasmine oil, 10 g of peppermint oil, and 10 g of grapefruit seed extract were added and dispersed to obtain a shampoo composition. The final shampoo composition obtained was confirmed to be a dark brown viscous liquid.

<Result>

As a result of the performance test, when tested by wrapping it directly on the tester's head, the overall foam was abundant and the cleaning power was maintained. The scalp felt cool after rinsing, and the touch after rinsing was also soft. However, not only was it difficult to pump due to its strong viscosity, but also the product changed over time due to hardening of the remaining liquid after use, so it was considered unsuitable. The performance evaluation was as shown in Table 2 below.

<< Example 1 >>

In general, it is assumed that the stratum corneum of the scalp is formed when foreign substances such as dust in the air and bodily fluids released as sweat from the human body meet. At this time, if you keep the scalp clean by removing the dead skin layer of the scalp surrounded by the hair, oxygen supply to the pores becomes more advantageous and blood circulation improves, thereby maintaining healthy hair follicles and strengthening hair roots. It can be effective in preventing hair loss and promoting hair growth.

As confirmed by the various evaluation items in Table 2, the present invention not only has good foaming power, excellent cleaning power, and excellent hairstyling power, but has the characteristics of low irritation to the scalp and excellent feeling of use.
